Review on Nathan Zipster Running Waist Black Men's Accessories by Chris Lapan

The first time I wore them was my first half marathon. As there was water on the route, all I needed to bring was my phone (iPhone 7), ID and some fuel (two squeeze bags of baby food). Everything fits perfectly, there is space. No bouncing. For the record, I have a 28" waist and 36" hips and bought the small one. It wasn't very tight but it stayed in place and I forgot it was there. While it claims to be water-resistant, it's definitely not sweat-resistant. My phone and ID were a bit wet, even in the zippered pockets.
